A programmable acoustic recording tag and first results from free-ranging northern elephant seals
A hydrophone-equipped tag recorded exposure to noise, as well as physiological and behavioral sounds, on free-ranging northern elephant seals (Mirounga angustirostris). The compact acoustic probe (CAP) consisted of the hydrophone, a thermistor, and a pressure transducer in a 36 cm long, 10 cm diamet...
